[releases/26.1] M365 Sync may fail as multiple identical permissions are added to the same temporary table (#3624)

In certain situations when we sync users from M365 they have multiple
identical permissions. This means we will attempt to add the same access
control to TempAccessControlWithDefaultPermissions multiple times.
Solution, if it's already added once, don't re-add it.
